The outer flanks want to be machined to be at least as small a radius
as the smallest part of the scroll that they can touch.
The inner flanks want to be the same radius as the absolute max of the
scroll radius.
I doubt that they are typically cut with any "slope" across the face.
They can only ever half line-contact with the scroll.
Andy has it right with the radius question. Make a program to those
radiuses and offset one 1/3 of the lead and one 2/3 of the lead of the
scroll.
